TECHNICAL FIELD

The present invention relates to benzazepine derivatives and salts thereof. The present invention also relates to medicines, comprising a benzazepine derivative and a salt thereof as an active ingredient, useful for diagnosing, preventing, and/or treating diseases associated with vasopressin receptors.

BACKGROUND ART

Vasopressin is an antidiuretic hormone and is known to function to increase blood pressure. Vasopressin Via receptor and vasopressin V₂ receptor are known as a subgroup of vasopressin receptors, each of which is associated with vascular constriction and reabsorption of water in the collecting duct.

Tolvaptan has a benzo-heterocyclic structure and is used for treating various diseases, especially as a vasopressin V₂ receptor antagonist. It has been known to be metabolized primarily by a hepatic metabolizing enzyme, CYP3A₄ (NPL 1 to 3). Various compounds have been known to have a benzo-heterocyclic structure (PTL 1 to 9), but no compounds having difluorine and hydroxy on positions 4 and 5, respectively, of a benzazepine ring among benzo-heterocycles have been known to have vasopressin antagonisms as both vasopressin V_(1a) and V₂ antagonists.

(1) Binding Inhibition Test for Rat V_(1a) Receptor (rV_(1a)R)

50 μg of V_(1a) receptor fractions derived from rat hepatic membrane were diluted with a reaction solution (100 mM Tris-HCl (pH 8.0), 0.1% BSA, 5 mM MgCl₂, 1 mM EDTA) and added to each well of a 96-well plate. A compound was added to each well in various concentrations (0.3 nM to 100 nM), and ³H-AVP was added thereto in the range of 1 nM to 3 nM. Reactions were carried out at 4° C. for 2 hours on the plate. Via receptor fractions were collected with a 96-well glass filter (Unifilter GF/B) after the reactions and washed with a washing solution (10 mM Tris-HCl (pH 8.0), 5 mM MgCl₂, 1 mM EDTA) three times, and then the radioactivity of ³H-AVP was measured with a scintillation counter.

(2) Binding Inhibition Test for Rat V₂ Receptor (rV₂R)

Rat V₂ receptor-expressed CHO cells (rV₂R—CHO) were incubated on 10% FBS-containing DMEM/F12 in a 24-well plate, and each cell was washed with D-PBS twice. A reaction solution (D-PBS containing 0.1% BSA and 0.05% sodium azide) comprising a compound in various concentrations (0.3 nM to 100 nM) was added to each well, and a certain amount of ³H-AVP was added thereto (100-fold dilution). Reactions were carried out at 4° C. for 2 hours on the plate. Then, each well was washed with D-PBS twice and 0.1N NaOH was added to each well. The cells were collected, and the radioactivity of ³H-AVP was measured with a scintillation counter.

(3) Calculation of IC₅₀

³H-AVP binding rate in the presence of a compound was calculated by the following equation. Binding rate (%)=(B−NSB)/(TB−NSB)×100 (B: Binding amount of ³H-AVP in the presence of each compound, NSB: Binding amount of ³H-AVP in the presence of 1 μM of unlabeled AVP, TB: Binding amount of ³H-AVP in the absence of 1 μM of unlabeled AVP)

The concentration (IC₅₀) where each compound inhibits 50% of ³H-AVP binding amounts was calculated using ³H-AVP binding rates and compound concentrations.

Results are shown below.

Test Example 2: Metabolic Stability Test

Reaction System and Incubation

According to methods of Obach and Jones, et al. (methods described in R. S. Obach, Drug Metab. Dispos. 1999 (27): 1350-1359 and H. Jones and J. B. Houston, Drug Metab. Dispos. 2004 (32): 973-982), the reaction system shown below was prepared and metabolic stabilities of test compounds (the present compounds and, tolvaptan) were evaluated using the reaction system shown below. Human liver microsomes purchased from Corning Inc. were used. Test compounds were dissolved in DMSO at the concentration of 10 mmol/L and then diluted with acetonitrile to prepare a 100 μmol/L solution for use in the test. The 100 μmol/L solutions were used in the experiment.

<Reaction System>

Test compound 1 μmol/L

Human liver microsome 1 mg/mL

Co-factor (NADPH and NADH) 1 mmol/L each

Magnesium chloride 5 mmol/L

100 mmol/L Potassium phosphate buffer (pH 7.4)

Number of samples: n=4

<Reaction Condition>

The reaction mixture without co-factors was pre-incubated at 37° C. for 5 minutes, and then the reaction was initiated by the addition of the co-factors. The mixture was incubated for 0, 5, 10, 20, 30, and 60 minutes after the addition of the co-factors. An aliquot of the reaction mixture was removed and added to a methanol solution containing an internal standard (IS) and mixed to terminate the reaction at each predetermined time.

Analytic Method

After the reaction was terminated, the mixture was separated by centrifugation and the supernatant was injected into a liquid chromatograph-tandem mass spectrometer (LC-MS/MS) to measure unchanged substances remained in the reaction system. The mass spectrometer was operated in a positive ion mode of the electrospray ionization (ESI) method. Unchanged substances and the IS were detected by multiple reaction monitoring (MRM) transitions using selected precursor and product ions set.

Data Analysis

The remaining ratios of test compounds were calculated by the following equation. Remaining ratio=(Peak area ratio of a test compound to IS at t minutes after incubation)÷(Peak area ratio of a test compound to IS at 0 minute)

The slope of X-axis (the incubation time) and Y-axis (logarithm of the remaining ratio) was calculated by a non-linear least square method. Hepatic intrinsic clearance (CL_(int)) was calculated by the following equation. CL _(int)(μL/min/mg)=−(Slope(min⁻¹))÷1(mg/mL)×1000

Results are shown below.

Test Example 3: Pharmacokinetics Study in Mice

Test Method

A pharmacokinetics (PK) study was performed using male ICR mice to compare the oral absorption properties of the present compounds with tolvaptan. A test compound was suspended in a 1% hydroxypropyl methylcellulose (HPMC) solution to be adjusted to the concentration of 4.5 mg/mL. The present compounds were used as the forms obtained in the above examples (including the amorphous form) for a test compound, or used after spray drying, if needed.

Male ICR mice (7-week old) were freely fed food and water and weighed on an electronic scale. Then, a test compound was orally administered at the dose of 30 mg/kg (15 mL/kg). After the oral administration, blood was collected from the abdominal vena cava under isoflurane anesthesia using a 1 mL heparinized syringe with a 26 G injection needle. Blood was separated by centrifugation at 4° C., 3000 rpm for 10 minutes to give plasma in a supernatant. The plasma concentration of a test compound was measured by LC-MS/MS.

Test Results

The following PK parameters were calculated using the mean plasma concentrations of unchanged substances obtained from two animals at each time point.

C_(max): Maximum plasma concentration (μg/mL)

t_(max): Time-to-maximum plasma concentration (h)

AUC_(inf): Area under the plasma concentration-time curve from administration to infinite time (μg h/mL)

The results showed that the C_(max) and AUC_(inf) values of the present compounds were higher than those of tolvaptan. Results are shown below.
